A couple years ago, we introduced you to the then 24-year-old taking on the challenge of explaining physics in one minute.

The now 26-year-old Henry Reich and Minute Physics, a YouTube channel that has nearly 2 million followers, is starting a series that talks about physics in just 9.999 seconds — a fancy way of saying no more than 10 seconds.

He’s calling it the PETS Show. To avoid confusion, in this case PETS stands for “physics explained in 10 seconds,” not Positron Emission Tomography, which Reich’s video noted is a method of making pictures with flashes of light from positrons and electrons “annihilating each other in your brain.”

So your first, official 9.999-second physics lesson is about the tides:

Your second video is about Fahrenheit, Celsius and Kelvin:

Reich will be posting the super-speedy snippets along with the usual Minute Physics videos, which seem long now, for the rest of the month. Stay tuned.
